Lethal is a deep plum with neutral-to-warm undertones and a matte finish. It had semi-opaque pigmentation, while the consistency was lightly dusty but not too thin and blended out decently. It would be easier to work with over a primer, but it was manageable on bare skin. I found this shade to be buildable to opaque coverage in two to three layers. It wore well for eight hours before creasing slightly. ColourPop Doe-a-Deer (LE, $6.00) is more shimmery (95% similar). Ciate Day Dream (LE, ) is cooler (95% similar).
